Memoir

How it works

From an address to an inspectable investigation.

Memoir investigates a public Ethereum or Base address in one workspace. It asks independent public sources for account facts, assets, intelligence signals, relationships, and chronological activity; keeps missing coverage visible; and lets the user inspect the evidence before optionally asking an AI model to explain a selected snapshot.

The investigation flow

  1. Enter one public address. Memoir accepts an Ethereum or Base 0x address. It never asks for a seed phrase, private key, signing permission, or wallet connection.
  2. Read sources independently. Account history, holdings, protocol state, public labels, sanctions data, and other signals can succeed or fail separately.
  3. Inspect one workspace. Account, assets and positions, public signals, direct relationships, and chronological activity remain separate modules in the same address record.
  4. Select what matters. Users can add timeline records and structured workspace evidence to a temporary analysis selection without changing the underlying ledger.
  5. Analyze and export. Optional AI receives only the selected snapshot and its coverage limitations. Reports retain the cited evidence and can be saved as a local PDF or portable dossier.

What works without AI

AI is not required to fetch or browse public records. The following remain deterministic and inspectable:

AccountAddress type, first indexed activity, chain counters, and current native balance
AssetsReturned token and NFT holdings plus admitted protocol positions
SignalsSource-attributed labels, exact public designations, contract verification, and reproducible metrics
ActivityA newest-first, virtualized ledger whose records keep their source references

What AI changes—and what it does not

AI can summarize, compare, and propose evidence-linked interpretations. It does not fetch a hidden version of the address, silently expand the selected evidence, or turn a public label into verified identity.

The analyzed snapshot is frozen when the request starts. Records loaded later do not silently enter an in-flight report. Every completed or failed report preserves the context used at that moment.

Users choose the provider and model. Hosted-provider credentials and prompts travel directly from the browser to that provider, not through a Memoir AI proxy.

How to read the result

  • Evidence is a returned onchain or public-index observation.
  • Signal is a named source's statement or a reproducible metric over loaded evidence.
  • Interpretation is an AI explanation that must cite supplied evidence or signal IDs.
  • Coverage records what responded, what was partial, and what remains unknown.
